I should also import print_function and unicode_literals from __future__ for Python 2.x compatibility, since I use print() once and never use bytes. I hadn't turned up any problems with 2.x without the __future__ imports, but it's nice to be explicit ;). Cheers, Trevor -- This email may be signed or encrypted with GnuPG (http://www.gnupg.org).
